Application filed January 22, 1923. Serial No. 614,122.

To all whom t may concern.'

Be it known that I, HENRY P. ROBERTS, a citizen of the United States ofAmerica, and a resident of Boston, in the county of Suffolk and State ofMassachusetts, have invented certain new and useful Improvements inBottle Caps, of which the following is a speciiication.

This invention relates to bottles caps and has for its object theprovision of means whereby a bottle may be hermetically sealed. Theinvention consists of a cap having inturned ears adapted to engage aflange on the neck of a bottle, combined with means for forcing saidears into gripping contact with said neck.

The invention further consists of a cap provided with a packing memberand having a non-revoluble threaded stem extending through a bar havinginturned arms for forcing said disk into gripping contact with a flangeon the neck of abottle, said stem having an adjusting .nut by which thecap maybe forced against the end of the bottle.

The invention further consists in certain novel features of constructionand arrangement of parts which will be understood readily by referencetothe description of the drawings and to the claims to be hereinaftergiven.

For the purpose of illustrating the invention, one preferred formthereof is shown in the drawings, this form having been found to givesatisfactory and reliable results, although it is to be understood thatthe various instrumentalities of which the invention consists can bevariously arranged and organized, and that the invention is no-t limitedto the precise arrangement and organization of the instrumentalities asherein shown and described, except as required by the scope of theappended claims.

Of the drawings:

Figure 1 represents a front' elevation of the upper end ofa bottle andhaving applied thereto a bottle cap embodying the principles of thepresent invention.

Figure 2 represents a plan of the same.

Figure 3 represents a side elevation of the same.

Figure 4 represents a vertical section through the bottle closing disk,on line 4, 4 on Fig. 1.

Figure 5 represents a p-lan of the blank from which the disk sup-portingbar is formed.

Figure 6 represents an inverted plan of the bottle closing disk with thepacking member removed, and

Figure 7 represents a vertical section of same on line 7, 7 onFig. 6. l

Similiar characters indicate like parts throughout the several figures'of the drawings.

In the drawings, 10 is a bar havin downwardly extending armsll, thelower ends of which are inturned kas indicated at 12, these inturnedends 12 being adapted to extend below a iange 13 on the neck 14 of abottle.

The bar 10has a cylindrical'opening 15 therein through which extendsthe-threaded stem 16 projecting upwardly from a cupshaped disk 17. Thiscup-shaped disk 17 has a cylindrical opening 18V centrally disposedtherein, in which is positioned the threaded stem 16, the lower end ofwhich is provided with a flat-sidedy head 19 positioned in a recess 20formed in the under side of the cup-shaped disk 17 l Positioned withinthe cup-shaped disk 17 is a resilient packing member 21 which is adaptedto rest upon the upper end of the neck 14 of the bottle.

The cup-shaped disk 17 is provided with oppositely disposed ears 22, theout-turned lower ends of which are positioned in o-penended slots 23rformed in the inturned ends 12 of thek arms 11. By thus positioning theears 22 in the slots 23, the bar 10 and the disk 17 are prevented fromrotatingy relatively to each other.

The outer end of the threaded stem 16 'has an adjusting nut 24 mountedthereon, the under face of which bears against vthe upper face of thebar 10. When the disk 17 is positioned upon the end of the neck 14 of abottle, with the ears 22 engaging the under portion ofthe liange 13, itis obvious that when the nut 24 is rotated clockwise about the axis ofthe stem 16, the bar 10 will be forced downwardly, thereby causing theears 22 to be moved toward each other into gripping contact with theneck of the bottle. Further rotation of the nut 24 will cause the disk17 to be forced against the sealingV the bottle.

All rotary movement of the bar 10 and disk 17 is prevented by theVriction oi' the packing member 2l in engagement with theY upper end ofthe neck 14e of the bottle.

lhenrit is desired to remove the cap from the bottle, the nut 24 isrotated contraclockwise and this movement will cause the pressure of thearms 12 on the ears 22 to be removed. The disk 17 may then be removedfrom contact with the end of the bottle by snapping the ears 22 over theflange 13 on the bottle neck 14.

This makes a very simple device to be used on various forms of bottlesto hermetically close the same until it is desired to secure access tothe contents of the bottle. Itis believed that the operationY and manyadvantages of the invention will be understood readily without furtherdescription.

Having thus described my invention, l claim:

1. A bottle cap consisting of a non-revoluble disk having oppositelydisposed downwardly extending ears adapted to engage a l flange on theneck of a bottle; a bar having arms engaging the outer faces of saidears; and means for adjusting said bar toward said disk to cause saidears to move toward each other and grip said neck.

2. A bottle cap consisting of a bar having oppositely disposed arms; anon-revoluble disk provided with a stem extending through an opening insaid bar and having downwardly extending ears adapted to be 'forcedtoward each other by said arms; and means for adjusting said bar towardand from said disk.

3. A bottle cap consisting of a nonrevoluble disk provided with athreaded stem and having downwardly extending ears adapted to engageatlange on the neck of a bottle; a bar provided with an opening throughwhich said stem extends and having opposite-ly disposed inturned armsadapted to force said ears into gripping contact with said neck; and anadjusting nut on the projecting end of said stem.

e. ik bottle cap consisting of a non-revoluble disk having oppositelydisposed ears adapted to engage a flange on the neck of a bottle andprovided with a threaded stem; a bar provided with an opening throughwhich said stem extends and having oppo sitely disposed inturned armsadapted to force said ears into gripping contact with said neck, saidarms having open-andai `slots vto receive said ears; and an adjifstingnut on the projecting end of said stemt 5. A bottle cap consisting of anon-revoluble disk provided with a threaded stem and having downwardlyextending ears adapted to engage a flange on the neck of a bottle; a barhaving an opening to receive said stem and provided with arms adapted toforce said ears into gripping contact vith said neck; means forpreventing the rotation of said bar relatively to said disk; and anadjusting Ynut on the projecting end of said stem.

6. A bottle cap consisting of'a non-revoluble cup-shaped disk providedwith a threaded stem and having downwardly extending ears adapted toengage a iange on the neck orn a bottle; a resilient packing member insaid cup-shaped disk; a bar having an opening to receive said stem andprovided Vwith arms adapted to force said ears into gripping contactwith said neck; means for preventing the rotation of said bar relativelyto said disk; and an adjusting nut on the projecting end of said stem.

7.
